【摘要】 本文利用有限元离散坝体与水体，给出了一种考虑水体压缩性时坝水系统基频的数值解法。对考虑水体压缩性与不考虑水体压缩性两种情况下坝水系统的基频及振型进行了比较。更多还原

【Abstract】 In the paper, a numerical method of solving the first freqency of dam -water system,with the compressive character of water by the finite element method is developed. The first frequency and mode of the dam-water system with the compressive or uncompressive character of water is compared.更多还原
